The problem is that jQuery is blocked by something or is just not loading. For example, when pressing the "click here if this was helpful" button or when typing something in the search bar, nothing happens. I've done some research and something which can block jQuery is "js/universal/custom.js" which is loaded, but either if it still loads or not, jQuery still doesn't work for those elements.
I don't understand why. Waiting for your answers! :D
Because you load jQuery AFTER the files that need it. Move it to the top of the includes.
Since you have inline JavaScript in the body that references jQuery, you will need to add the script reference into the head.
Also your HTML is invalid, you have divs inside of your head tag.
If you look at the developer console (F12 on most browsers), you'll see a bunch of errors that say that jQuery is not defined. You need to put the jQuery tag before any of your other scripts are declared, preferably (really best practice) in the .
jQuery, however, is loading. It is just loading after you're other scripts have been loaded and executed.
You can test this by opening the developer console and typing
$('#but_full28').bind('click', function() {alert('Clicked');})
When you click on the "click here if this was helpful" div, it'll give you an alert.
TLDR: Add the jQuery script tag before all of your other script tags in the head and you'll be all good.

This question have been already treated on the internet but i dont find a simple answer.
I would like to load only thoses javascript files and css, before starting to run the body my website.
I'm using packery.js, but when my website appears at first, my divs are misplaced. When i reload the page, everything gets back in place.
Is there a way to say : does all css and js files have been donwload? Yes? Ok run the body.
Thank you
There isn't a lot of information you provided which would help us solve the issue directly, however couple of things...
Make sure all your scripts and styles links are places in the head tags. The HTML page gets rendered in browser Top-Down. I.E. It'll load any files from HEAD tags before the body is reached, same thing if you want your scripts to be loaded after the body is loaded.. just put them at the bottom, before the BODY closing tag.
Using JQuery would be the fastest solution if you wanted to perform some functionality after your page has loaded (I know there isn't a JQuery tag, however thought providing a JQuery answer could be advantageous.
$(document).ready(function()
{
//Document Loaded, Put code you want to execute here.
}
I'm pretty sure this was somewhere discussed, but I cant seem to find it anywhere. I would really appreciate if anyone could point me to the right direction.
I have setup a dialog which opens and closes just fine. I need to load dynamic content in it and so Im using this:
$('#dialog').load("somepage.php?document=1");
This load up correctly and everything works pretty much fine except the fact that once I close the dialog and then open it with some different query string (e.g. with document=2) I can see that there are still contents of document=1 loaded in DOM.
This causes issue when there is javascript function in the Loaded page because than it gets executed twice. (well the number of times I load documents so its pretty much unusable).
I have tried clearing the dialog:
$('#dialog').html("")
But that didnt help much.
Does anyone have any idea what could help?
Instead of just closing the dialog, destroy it:
$('#dialog').dialog("destroy");
That should clear the dialog back to its initial state:
https://api.jqueryui.com/dialog/#method-destroy
If you want to just load part of a page, you can always do the following: Let's say I want a specific div only.
$('#dialog').load("somepage.php?document=1 #myDiv");
Furthermore, I don't know what you're closing your #dialog with, but if it was something with an id of myButton, you'd do:
$(document).on("click", "#myButton", function(e) {
// To keep div within DOM and empty
$("#dialog").empty();
// To get rid of div (you would have to re-append #dialog every time)
$("#dialog").remove();
});
All this being said, .load() doesn't actually execute any scripts from your loaded page. If you were to use $.post() or $.get(), you could strip out the <script> tags yourself.
Best of luck!
I'm experiencing an issue (which I still need to fix) where my entire page does not load. It gets cut off in the middle of an element.
Is there a way using jquery or javscript to do something like:
if (some element has not loaded yet) {refresh the page}
I was thinking of just putting <div id="end_of_page"></div> at the bottom of the page, and checking if that was rendered, if not, i'll know something went wrong and can reload to try again.
thanks!!
Is there a way using jquery or javscript to do something like:
if (some element has not loaded yet) {refresh the page}
You can do that, yes. Put this in the head after including jQuery:
<script>
jQuery(function($) {
if (!$("#end_of_page")[0]) {
// Something went wrong, load again
location.reload();
}
});
</script>
You'll enter the body of the loop (and so, force a reload) if the end_of_page element doesn't exist as of when the jQuery ready event fires (which is meant to be when the page is done loading).
But: Better by far to figure out why your page is getting cut off half-way through and solve that. This sort of workaround is not a solution.
You can use
$(document).ready(function(){
// code here
});
that code will only run when the page has loaded. A convenient shorthand is:
$(function(){
// code here
});
assuming your jQuery object is $. To finish your requirement, you can have a variable that is set within the load function, then use a timer set at the start of the page to check for it. If it's not there, reload.
Personally, I think you should invest some time into figuring out why your pages only half-way (Firebug or the Chrome Inspector may help you do this, it might be a resource in your page that is causing it to hang, and since most HTTP requests are only made 2 at a time per hostname, it might be waiting for that to return before fetching the rest).
Might be a server-side issue OR some script or library is stealing your fish $ (AKA: 'Dollar').
I'll rather suggest you to debug your code instead of refreshing the page trying to fix issues.
Make sure your scripts are in the head of your document, and jQuery + your jQ functions right before the closing </body> tag wrapped in:
(function($){ /*your functions*/ })(jQuery);
I have no idea how to describe this accurately/intelligently because it seems to be completely impossible, yet there must some reason for it.
I am trying to leverage jquery, jquery-ui, qtip (tooltip for jquery) and highcharts (javascript charting), but for purpose of post I could just as easily been only using jQuery and jQuery-UI.
If I include my <script/> tags at the bottom of my <head/> element I get an error trying to call the .slider() extension to configure my sliders. But if I put the <script/> tags right before the closing of my <body/> element then everything works. To illustrate, the following will not work (obviously some pseudo code below):
<head>
<script jquery.js/>
<script jquery-ui.js/>
</head>
<body>
... html ...
<script type="text/javascript">
$(document).ready(function () {
$(".slider").slider( { .. options .. } );
} )
</script>
... more html *including* the .slider elements
</body>
However, if I move the two jQuery script tags to be right above the </body> closing element things work. When the script tags are in the head element and I debug my application, basically the page does appear to have completely loaded and Visual Studio highlights the line calling the .slider() function saying it doesn't know what slider() is. Looking at the call stack, it appears to be correctly calling it from the document ready function...the mark up all appears to be there as well, making me believe the document truly is ready.
Now I didn't include things that are required by asp.net 1.1/2.0 site in my pseudo code, namely a <form/> element with runat="server' and the use of a <asp:ScriptManager/> tag (we needed that for parsing monetary values from different cultures leveraging Microsoft Ajax). I can't believe they would be causing the problem, but maybe they are. Additionally, asp.net injects several of its own script sections (i.e. for validation, post back, etc.)
Regarding the form tag...all the html and document.ready markup would be inside the form tag, while the script tags are always outside of the form tag (either above it, in the head or below it at the bottom of the body).
Obviously I could leave the script tags at the bottom, and I very well may end up doing that, but I am trying to get a clean 'template site' of which to use when creating new client sites and it just feels wrong that I have a restriction forcing me to put those tags at the bottom of the html. I'm sure our framework code (or maybe asp.net's) is simply inserting something that is causing problems/conflicts with jQuery, but I don't really know how to go about debugging/diagnosing what that problem is. So if anyone has any suggestions I'd greatly appreciate it.
It looks like jQuery 1.3.2 is being loaded by ASP.NET (see your second WebResource.axd). The two library versions are overwriting each other. Thus the reason it works when you load 1.6.2 at the end of the page.
Interesting problem here from some inherited code I recently looked at. I'm trying to add a compression module to a project. It is loading all the JS and CSS files, combining them, minifying them, and compressing them. I've tried a number of solutions, but all of them have one fatal problem.
I have some javascript that is being loaded via Page.ClientScript.RegisterClientScriptBlock in the PreRender of the MasterPage. The compression module is loading as a Script Tag link in the MasterPage, but when I run the page... the code from the PreRender is lopped on top and is giving me a '$ is undefined' error, telling me jQuery isn't loaded yet.
Furthermore, I can't seem to get past the same problem when it comes to inline javascript on content pages.
Any ideas as to what is causing this? Enlighten me as I have no clue.
If have done this before with RegisterStartupScript (instead of RegisterClientScriptBlock) and called the $(document).ready(function() from WITHIN that script.
If the script tag link that eventually expands out to jquery is not in the head, but in the body of the page, then $ will be undefined when the script block executes, unless it is included in the html before the opening <form /> tag in the rendered html, which I understand is where RegisterClientScriptBlock spits out its script (just after that opening tag).
If this is not the case, and the joined/minified script is in the head, then I'd use a browser debugger such as Firebug or IE Dev Tools to verify that the jquery script is being correctly included in your combined script.
I know this answer is late to the party, but try calling ClientScript.RegisterClientScriptBlock in your OnPreRenderComplete (rather than OnPreRender) handler. This inserts the code later in the page rendering process.
All your jQuery code should be written inside the DOM-ready function:
$(function() {
// your code here
});
indipendently from where you place it in the page, 'cause the jQuery() function isn't avalaible before.
